Question

An electron has a spewd of 500m/s
with uncertainty of 0.02%. What is the uncertainty in locating its position?

Answer 1

Answer:

Explanation:

We know from Heisenberg's theory of uncertainty that

X.P is greater than or equal to h/4π ( h = 6.6 × 10^-34 JS)

Given V/V = 0.02

V= 2/100× 500 = 10 m/s.

Now the values can be put in the equation above mentioned.

NOTE:- P= MV

M(mass of electron) = 9.31 × 10^-31 kg

V= 10 m/s

P= 93.1 × 10^-31 kgm/s
